In order to easily return to relevant information and to be able to collaborate on a search, you can set aside documents to return to later.
When processing information within a search, you can apply a "Favorites", i.e. a backup, of the documents that interest you.
The icon "Favorites” 
appears systematically at the top right of each article.
To save one or more documents, simply click on the star icon of the document(s) in question. Once checked, it will turn yellow to indicate that the document has been added to the favorites.
To find all your bookmarked items, simply click on "All filters" and then select "Favorites".
You will then find all the documents you have saved and be able to analyze the ecosystem related to these articles.
When you share your search with one or more members of your team, they will be able to consult the documents you have set aside thanks to this functionality. They in turn will be able to either remove them from the list or apply "Favorites" to other documents, enabling better collaboration.
